MODIFIED LITHOTOMY/PELVISCOPY SURGICAL DRAPE

Abstract: Disclosed herein is a surgical drape which while being available for all surgical procedures, is particularly well suited for modified lithotomy and pelviscopy procedures. In both procedures, the patient is usually laying face-up on the operating room table with the legs extended into the air off the end of the table. The drape of the present invention provides added coverage in the areas beside the patient and below the table due to the overlapping nature of the components of the surgical drape (14, 16; 56, 78, 80).

Description: MODIFIED LITHOTOMY/PELVISCOPY SURGICAL DRAPE BACKGROUND OF THE INVENTION The present invention relates to a surgical drape for number of procedures including those when the patient is the lithotomy or trendelenburg positions. More specificall the present invention relates to a surgical drape wi improved coverage of the operating room table and patient. The number and type of surgical procedures are constant on the rise. As new surgical procedures are developed, dra manufacturers will oftentimes design drapes which are mo suitable for one or more type of procedures than another dra design. Many surgical procedures are performed using surgic drapes called "T-sheets". These sheets generally resemble t shape of a T and are constructed with a large sheet material forming the top portion of the T horizontal attached to another sheet of material that is perpendicul to the larger sheet. Many of these sheets are sold laparoscopy sheets and are used for surgical procedures fr the perineal area to the abdominal area. These drapes wi typically have one or two fenestrations with the low fenestration adjacent the bottommost portion of the providing access to the perineal area while the upp fenestration provides access to the abdominal area. Anoth such drape with a similar configuration is a lithotomy drap Both of these types of drapes are available from a number manufacturers including Kimberly-Clark Corporation of Neena Wisconsin (assignee of record) , Baxter Healthcare Corporati of Deerfield, Illinois, Johnson and Johnson Medic Incorporated of Arlington, Texas, and Boundary Healthca Products Corporation of Columbus, Mississippi. In connection with the surgical procedures using the drapes, it is common practice for the operating room personn to move from the perineal area to the abdominal area of the patient during the surgical procedure. Typically during these procedures the patient is lying on the operating room table with his/her legs in the air in what are commonly referred to as the lithotomy and trendelenburg positions. In these positions, the long central portion of the "T-shaped" drape is positioned between the legs of the patient with the fenestration(s) covering the appropriate surgical site(s). The remainder of the drape, i.e. the upper horizontal portion of the drape forming the top of the T, is draped laterally across the upper portion of the patient. When operating room personnel move to the outside of the patient's legs to gain access to the patient's abdomen, the person is standing in an area where there is little or no coverage of the surgical table. One problem with the aforementioned drape design is that it does not provide total coverage and thus sterility of the operative site in this area of the patient/operating room table during the surgical procedure. There is therefore a need for a surgical drape providing such added coverage and protection. One solution has been to provide a surgical drape of the aforementioned design with built-in leggings to cover the patient's legs while in an upright position. While this surgical drape design provides a greater sterile barrier than the preceding drape designs, the design is very difficult to unfold and lay out over the patient and operating room table. SUMMARY OF THE INVENTION In view of the foregoing problems and disadvantages with previous surgical drapes, it is an object of the present invention to provide a surgical drape with side attachments or "wings" that will provide greater coverage of the patient and operating room table in the area to the side of and below the patient's legs. The surgical drape of the present has two general embodiments. In the first embodiment, the surgical drape is made from a ainsheet including a first portion and a second portion. The first portion of the surgical drape defines a cut-out section. The cut-out section is formed from at least two side edges each of which extend inwardly from an edge of the mainsheet. The cut-out portion can have a variety of shapes but usually the two edges will be generally parallel to one another or angled inwardly so that the ends of the edges adjacent the edge of the mainsheet are closer together than the opposite ends of the two edges which terminate at a point in the interior of the mainsheet. The second portion of the mainsheet of the surgical drape is connected to the first portion of the mainsheet, usually at a point above the cut-out section in the first portion so that the second portion covers the cut-out portion in the first portion of the mainsheet and overlaps the two side edges of the cut-out portion. To provide access to the abdominal and perineal areas of the patient covered by the surgical drape, the mainsheet can include a first fenestration located in the first portion and a second fenestration located in the second portion. If desired, a flap of material may be attached to the mainsheet such that the flap can be pivoted to cover at least one of the first and second fenestrations. In the second embodiment, the mainsheet is generally "T- shaped" and includes a first portion corresponding to the upper portion of the "T" and a second portion corresponding to the lower portion of the "T". The first portion in this embodiment has a top edge, a left bottom edge and a right bottom edge with a pair of opposed side edges connecting the top edge respectively with the left bottom edge and the right bottom edge. The second portion includes a bottommost edge, a left side edge and a right side edge. Collectively these edges form the outline of the "T". Attached to the mainsheet are a left flap portion and a right flap portion with the left flap portion extending and covering an area exterior to the left bottom edge and left side edge of the mainsheet. The left flap portion includes a left overlap edge which overlaps the left side edge of the second portion of the mainsheet. In the same fashion, the mainsheet includes a right flap portion with a right overlap edge which extends and covers an area exterior of the right bottom edge and the right side edge with the right overlap edge overlapping the right side edge of the second portion of the mainsheet. As with the other embodiment, the first portion may include a first fenestration and a second fenestration so as to provide access to the abdominal and perineal areas of the patient. In addition, a flap may be attached to the mainsheet and pivotally adjusted to cover at least one of the first and second fenestrations. Lastly, the left overlap edge of the left flap portion and the right overlap edge of the right flap portion may be generally parallel to one another or angled inwardly. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a top plan view of a modified lithotomy/pelviscopy surgical drape according to the present invention. Figure 2 is a top plan view of another embodiment of a modified lithotomy/pelviscopy surgical drape according to the present invention. Figure 3 is a perspective view of the surgical drape of Figure 2 positioned atop a patient. DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, there are at least two general drape designs corresponding to the present invention. The first, shown in Fig. 1, is based upon a "U-shaped" design with a second piece of material covering the center portion of the "U". The second design, shown in Fig. 2, more closely resembles a "T-shaped" design with wings attached to the "T" portion. It should be appreciated that various modifications and changes can be made to these two designs without departing from the spirit and scope of the present invention. For example, the drapes can be made from one or multiple pieces of material and still provide the same features and functions. Referring specifically to Fig. 1, there is shown a surgical drape 10 made from a main sheet 12 including a first portion 14 and a second portion 16. The main sheet 12 including the first portion 14 and the second portion 16 can be made from any material or materials suitable for use in drape constructions. Examples of common draping materials include paper, plastic film, woven material such as linen, nonwoven materials, reinforced materials, foams, and laminates. Suitable nonwoven materials include spunbond, meltblown and staple fiber material such as bonded carded webs. One material particularly useful for the present invention and manufactured by the assignee of record, Kimberly-Clark Corporation, is a spunbond, meltblown, spunbond laminate sold under the trademark EVOLUTION* III fabric. This material can be made in accordance with the teachings of U.S. Patent No. 4,041,203 to Brock, et al., which is assigned to the assignee of record and is incorporated herein by reference in its entirety. Turning again to Fig. 1, the first portion 14 of the main sheet 12 defines a cut-out section 18 extending inwardly from an edge 20 of the main sheet 12. The cut-out section 18 is formed from at least two side edges 22 and 24 which extend inwardly from the edge 20 of the main sheet 12. To perform surgical procedures within the abdominal area of the patient, the first portion 14 of the main sheet 12 may be provided with a first fenestration 26 which is usually located between the cut-out portion 18 and the top edge 28 of the first portion 14 of the main sheet 12. If desired, the fenestration 26 may be located in other areas of the first portion 14 of the main sheet 12. The second portion 16 of the main sheet 12 shown in Fig. 1 is shown as having a generally rectangular shape. Other shapes are also contemplated to be within the scope of the present invention provided the second portion 16 is of sufficient size to cover the cut-out section 18 in the first portion 14 of the main sheet 12. Generally, the second portion 16 will be attached or connected to the first portion 14 in the area of the first portion 14 between the cut-out section 18 and the top edge 28 and more particularly between the cut-out section 18 and the_fenestration 26. The second portion 16 is of sufficient size to cover the cut-out portion 18 in the first portion 14 in a manner so as to overlap the two side edges 22 and 24 of the cut-out portion 18. By "overlap" it is meant that one piece of material lays on top of the other. In Figure 1, the two side edges 22 and 24 are underneath the second portion 16 but still overlap the second portion 16. It is usually desirable that the degree of overlap be at least about 1 to 2 inches or greater so that during use, the overlap is still maintained. If desired, the second portion 16 may be provided with a second fenestration 30 to permit surgical procedures to the perineal area of the patient. Also if desired, the drape 10 may be provided with a flap 32 pivotally attached to the drape 10 such that it may be pivotally flipped back and forth to cover either the first fenestration 26 or the second fenestration 30. Referring to Fig. 3, the surgical drape 10 is shown positioned on an operating table 34 with the majority of the first portion 14 above the cut-out section 18 being positioned atop the table 34 with the remainder of the drape 10, including the second portion 16 extending down over the side of the table. In use, the patient (not shown) lies underneath the drape 10 with the first fenestration 26 being positioned adjacent the abdominal region of the patient. The legs of the patient (not shown) extend through the cut-out section 18 and are often placed in stirrups (not shown) attached to the table 34. Next, the second portion 16 of the drape 10 is passed over the perineal area of the patient and the second portion is allowed to hang down over the side of the table in such a fashion so that the second portion 16 overlaps the two side edges 22 and 24 of the first portion 14 thereby providing a greater degree of coverage of the patient and the surgical table 34 than with previous surgical drape designs. As shown in Figs. 1 and 3, the two side edges 22 and 24 are generally parallel to one another. If desired, the two side edges 22 and 24 may be angled inwardly toward one another to provide an added degree of overlap between these edges and the overlapping part of the second portion 16 of the surgical drape 10. A second embodiment of a surgical drape according to the present invention is shown in Fig. 2. In this embodiment, the drape 50 includes a main sheet 52 including a first portion 54 and a second portion 56. As can be seen, the first and second portions 54 and 56 form a generally "T-shaped" design with the first portion 54 forming the cross-bar of the "T" and the second portion 56 forming the main stem of the "T". As with the design shown in Figs. 1 and 3, this design may be made from the same types of materials as described above and also may be made from one or more pieces of material. Referring to Fig. 2, the first portion 54 of the main sheet 52 includes a top edge 58, a left bottom edge 60, a right bottom edge 62, and a pair of opposed side edges 64 and 66. The second portion 56 includes a bottom-most edge 68, a left-side edge 70, and a right-side edge 72. As shown in Fig. 2, the first portion 54 and second portion 56 of main sheet 52 are formed from one piece of material. To permit access to the abdominal region of a patient (not shown) the first portion 54 defines a first fenestration 74 located between the top edge 58 and the left and right bottom edges 60 and 62. To permit access to the perineal area of the patient (not shown) the second portion 56 may define a second fenestration 76 located between the first portion 54 and the bottom-most edge 68. To provide increased coverage of the patient and operating table, the drape 50 in Fig. 2 includes a left-flap portion 78 and a right-flap portion 80. The left-flap portion 78 either extends from or is attached to the first portion 54 adjacent or at the left-bottom edge 60 and includes a left- overlap edge 82 designed to overlap all or a portion of the left-side edge 70 of the second portion 56 of the drape 50. Generally, the left-flap portion 78 will extend and cover an area exterior to the left-bottom edge 60 and the left-side edge 70. In the same fashion, the right-flap portion 80 performs the same function as the left-flap portion 78 but on the opposite side of the second portion 56 of the drape 50. Consequently, the right-flap portion 80 extends and covers an area exterior to the right-bottom edge 62 and the right-side edge 72 with the right-flap portion 80 overlapping all or a portion of the right-side edge 72 of the second portion 56. As with the design shown in Figs. 1 and 3, it is generally desirable to have at least a 1 to 2 inch overlap between each of the flap portions and the side edges of the second portion of the main sheet 52. As with the design shown in Figs, l and 3, the design in Fig. 2 may have left and right overlap edges 82 and 84 which are generally parallel to one another or angled inwardly as specifically drawn in Fig. 2. In fact, the degree of angling of the left and right overlap edges 82 and 84 can be sufficiently severe so as to cause the two edges to overlap one another (not shown) and even be attached to one another if so desired so as to further maximize the degree of isolation of the patient and surgical table (not shown) from the sterile field of operation. In the same fashion as the embodiment shown in Figs. 1 and 3, the second portion 56 may be provided with a second fenestration 76 and a flap 86 may be pivotally attached to the drape 50 such that it may be pivotally flipped back and forth to cover either the first fenestration 74 or the second fenestration 76. Use of the surgical drape 50 shown in Fig. 2 is identical to the use described with respect to the surgical drape 10 shown in Figs. 1 and 3 with the advantage being the added degree of isolation of the patient and operating room table due to the use of the wings or flaps 78 or 80 which overlap the second portion 56 of the drape 50. Having thus described the invention in detail, it should be apparent that various modifications and changes can be made in the present invention without departing from the spirit and scope of the following claims.
